Twenty rabbits were introduced to Australia in 1788. Since they had no natural predators in Australia, the rabbit population grew exponentially. The population of rabbits in Australia, P(t), in terms of years since being introduced, t, can be represented by the function below.

P(t) = 20(2)t
What is a reasonable domain and a reasonable range for the problem situation?
Domain: t ≥ 20

Domain: t ≥ 0
Range: P(t) ≥ 20
Domain: t ∈
Range: P(t) ≥ 0
Domain: t > 0
Range: P(t) ≥ 20
